Information on range and speed

For a displacement boat making way through the water, the required propulsive power increases in proportion to the cube of the speed. This means that if you want to double your speed, you need eight times as much power.

And vice-versa, a small reduction in speed is enough to increase the achievable range substantially.

The Torqeedo Ultralight's on-board computer calculates the remaining range constantly, by linking the motor's consumption data with the charging level of the batteries, and the speed over the ground from the GPS. This allows you to read the remaining range in real time from the motor display or the smartphone app TorqTrac.

Tips

Ultralight 403 C FAQ

When the battery is completely discharged it takes approx. 10,5 hours to fully recharge it.

With the solar charger 50 W (accessory) you can charge anytime, during travel and while the sun is out.

What useful life can I expect the lithium batteries to have?

The life expectancy of lithium batteries in recreational use is, more or less, independent of charging cycles.

There is no memory effect either, i.e. you can fully charge them after each trip irrespective of the charge status shown in the display.

Generally speaking, a capacity loss of approx. 4 % per year is to be expected. Capacity loss will, however, accelerate if the battery is permanently exposed to heat. Also storing the battery always fully charged will accelerate ageing.

There are no concerns about using the battery in high temperatures, we recommend that you take the battery out of the sun and store it in a cool place after use.

Your battery must be returned to a Torqeedo Service Centre for service 8 years after the date of manufacture.
